  2. Time analysis Time analysisgoals: - Howmuchtime is neededtoimplementtheschedule? - Whencan I start and finishtheactivitiesattheearliest? - Whencan I start and finishtheactivitiesatthelatest?

  3. Activities A list of allactivitiesrequiredtocompletethe project. The timethateachactivitywilltaketocompletion. The dependenciesbetweentheactivities.

  4. Basic rules • Starting point and terminus • Arrows, circles • Activitiestime • ES,LS,EF,LF • Dummy

  5. 4 activitiesexample

  6. ES, EF, LF, LS ES - earliest start time EF- earliestfinishtime LF- latestfinishtime LS- latest start time

  7. ES, EF, LF, LS Formulas • Ei = ESij • Ej = EFij= ESij+tij • Li = LSij =LFij-tij • Lj = LFij

  8. The timecourseanalysis • TFij– totalfloat, TFij= Lj-Ei-tij = LFij-ESij-tij • FFij– free float, FFij= Ej-Ei-tij • IFij– independentfloatIFij= Ej-Li-tij • CFij – conditionalfloatCFij= TFij-FFij

  9. The timecourseanalysis The Forward pass (first phase) gives the turnaround time and the earliest possible occurence of events. The Backward pass (second phase) gives the latest possible occurrence of events.
